Koyorad is proud to introduce the first high-performance radiator for the FL5 Honda Civic Type R. This all-aluminium application features Koyorad’s high-density Hyper Core, increasing thickness by over 50% compared to the stock radiator. The result is greater heat capacity and improved endurance, especially under track conditions.
